A medium drive of a steel hub of a gear with an outside diameter of 80 mm on a steel shaft is required. a) Make the dimensional decisions for a 49-mm basic size with a medium drive fit for the hub and shaft, and specify dimensions with tolerances for the shaft and the hub bore for the fit. b) When the interference pressure “p” is at a minimum (p at δmin) for the specified tolerances how much torque (in Nm) can be transferred with the medium drive fitted assembly if the steel to steel friction is 0,8 and the hub of the length is 170 mm.
